Desirable Difficulties

Also called Productive difficulty

Conditions that slow learning in the session often improve retention and transfer afterwards.

Bjork's distinction is between performance during practice and learning measured later, and the two frequently move in opposite directions. Spacing, interleaving, testing and reduced feedback all make the session feel worse and the retention better, which is why learners reliably choose the method that teaches them least.

  • A course that gets the best feedback forms produces the worst results at six months.
